Customer Question

I have a 1992 Lexus that I put a 1994 engine and wiring. I need the wiring schematics for the fuse box under the hood and the under the dash top plug on the ECU.JA: Have you checked the manual yet? Most vehicles have two fuse panels.Customer: Owners manual only give the fuses location. I need the wiring location on the plug in. Wire colors are different.JA: What is the model of your '92 Lexus?Customer: Es300JA: Are you fixing your vehicle yourself? What have you tried so far?Customer: YesJA: Anything else you want the mechanic to know before I connect you?Customer: No

The fuse box in question is located on the left inner fender. It's 1994 box on a 1992. I have three wires on the vehicle that do not have a match. The White plug with 8 plugs slots, has white wire located in slot eight from 92 no matching wire on 1994 fuse box. The black plug has two small white wires this plug also has 8 slots wires are in 1 and 8. What does these wires operate. They plug well plug in the old fuse box and the 1994. But the car would not crank over. So I went to the junk yard and cut the plug and wires from a 1994. At first look, the wires match find. The same for the ECU, I understand that some wires will not be used do to passenger air bags. On the ECU I have red/blue with silver dots, Lite green/red with silver. Green/red with silver dots and black/white wire with silver and black white don't have a matching color on the 1994 ECU. All should be connected. Again I understand that the 1994 ECU will have wires that are needed. But the wires on the 1992 should be connected for the vehicle to operate. What do I do?
